Description
Technical field
The present invention relates to a kind of structure of fine arts propelling pencil, belong to pen technology field processed.
Background technology
Wooden and paper-roll pencil is write conveniently to people's work, learning tape, but consumes again a large amount of valuable forest reserves simultaneously.Existing wooden and paper-roll pencil needs volume to cut penholder and is fined away by pen core just can write, when 6-7cm used by pen, often thrown into dustbin because holding a pen inconvenience, volume cut after paper, wood chip cannot reclaim use especially, cause very large waste, and pencil-lead exposes easily disconnected core.Therefore, need a kind of continuous core, pen core utilization rate high, economize on resources, the pencil of environmental protection.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of fine arts propelling pencil improving pen core utilization rate is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of fine arts propelling pencil, comprise pen core, penholder, pen core propeller, pen core retaining core pipe is provided with from top to bottom successively in described penholder cavity, pen core is placed in pen core retaining core pipe, it is characterized in that, described pen core propeller is made up of nut, screw rod, riffled tube, and described nut is fixedly installed in the middle part of penholder cavity, and described screw flight matches with the screw thread of nut, riffled tube respectively; Described screw rod is placed in riffled tube cavity, and its lower end screws in nut, and is placed in above pen core, and screw rod, pen core are coaxial; Described riffled tube upper end is provided with rotary handle, and rotary handle is placed in outside the port of penholder upper end, and rotary handle is connected with riffled tube by cylindricality contiguous block, and riffled tube rotates clamping by cylindricality contiguous block and penholder inwall.
Described cylindricality contiguous block sidewall is provided with annular protrusion, and penholder inwall is provided with the cannelure matched with annular protrusion, and riffled tube is rotatably connected in penholder cavity by annular protrusion, cannelure.
Described rotary handle external diameter is greater than penholder internal diameter, and equal with penholder external diameter.
Described pen core retaining core pipe outer wall is provided with spacing block set, and pen core retaining core pipe is fixed in penholder inner chamber by spacing block set.
The length of described screw rod is greater than the length of pen core.
Described screw diameter is less than the internal diameter of pen core retaining core pipe, and is more than or equal to the diameter of pen core.
On described screw rod, the spacing of adjacent thread is 3-6mm.
In the present invention, pen core propeller is made up of nut, screw rod, riffled tube, and nut is fixed in penholder inner chamber.The present invention needs knockout in use, only need pin penholder on the other hand, pin rotary handle on the other hand, by rotating rotary handle clockwise or counterclockwise, cylindricality contiguous block rotates in penholder cavity, thus drive riffled tube to rotate, screw rod rotates along with riffled tube, because screw rod screws in nut, nut is fixed in penholder cavity, so screw rod can rotate and turn advance in nut along with riffled tube, thus screw rod moves below penholder, final pushing pen refill skids off outside nib, realizes the continuous knockout of pencil.The present invention is not when using, penholder can be pinned on the other hand, pin rotary handle on the other hand, counterclockwise or the rotary handle that turns clockwise, screw rod is moved above penholder, after there is space between pen core and screw rod, props up pen core tip, pen core being return in penholder, guaranteeing pencil continuous core when not using.
The setting of pen core retaining core pipe is that protection pen core is by its continuous core, and the spacing block set on pen core retaining core pipe outer wall is to make pen core retaining core pipe better be fixed in penholder in order to make pen core firm in penholder cavity.The length of screw rod is greater than the length of pen core, and the diameter of screw rod is less than the internal diameter of pen core retaining core pipe, and is more than or equal to the diameter of pen core, even if pen core is also left several centimeters after using for a long time, screw rod also can be allowed pen core to be ejected penholder and continue outward to use.On screw rod, the spacing of adjacent thread is 4-6mm, revolves the rotary handle that turns around, and can ensure pen core knockout 4-6mm.
The present invention is skillfully constructed, and structure is simple, and manufacture easily, cost is low, continuous core, and pen core utilization rate is high, economizes on resources, environmental protection, and user can be assisted to grasp correct holding posture, has the wide market space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of pen core retaining core pipe in the present invention;
In figure: 1 pen core, 2 penholders, 3 pen core retaining core pipes, 4 nuts, 5 screw rods, 6 riffled tubes, 7 rotary handles, 8 cylindricality contiguous blocks, 9 annular protrusions, 10 spacing block sets.
Detailed description of the invention
A kind of fine arts propelling pencil, comprise pen core 1, penholder 2, pen core propeller, pen core retaining core pipe 3 is provided with from top to bottom successively in penholder cavity, pen core is placed in pen core retaining core pipe, pen core retaining core pipe 3 outer wall is provided with spacing block set 10, and pen core retaining core pipe is fixed in penholder 2 inner chamber by spacing block set.
